@andrewteg @ wp support @ all other users
Again me … but already with more news on this error ??

Just the moment I remembered regarding the two different link structures in this error message

Load denied by X-Frame-Options: https://my-subsite-domain.de/wp-admin/customize.php does not permit framing by https://www.my-multisite.de/my-subsite/wp-admin/customize.php?et_customizer_option_set=theme. (unknown)

that I have set up in the domain mapping of my subsite the following:
1. https://my-subsite-domain.de (set to primary)
2. https://www.my-subsite-domain.de
3. https://www.my-multisite-domain.de/subsite-folder

So, now I changed the primary domain to the 3rd, the domain with multisite link structure, https://www.my-multisite-domain.de/subsite-folder, and directly the customizer preview was loading and works perfectly again.

But here the problem is now, that if you call your website like https://www.my-subsite-domain.de or without www in a browser, it will be forwarded to https://www.my-multisite-domain.de/subsite-folder, that means the visitor will see the multisite link of your subsite.

So this means if the customizer would load the preview in the iFrame independent on which primary domain set up in domain mapping, all would running perfectly. Any idea from the users and WP here, how this problem can be solved?

Thanks for helping. Best, dise?or

I have tested it, I changed both urls, siteurl and homeurl, the preview is visible, but then I only can login to the subsite with the direct url like my-domain.de/wp-admin. But this I don’t want, because I don’t want to login on each subsite extra, I want to login to multisite backend and from here to choose the subsite.

So I wanted to search in the WP and theme core files (php, js etc.) where this preview will be activated/loadd. I activated in Firefox the tools of the web developer and here I got the error at the tab “JS”:

Load denied by X-Frame-Options: https://my-subsite-domain.de/wp-admin/customize.php does not permit framing by https://www.my-multisite.de/my-subsite/wp-admin/customize.php?et_customizer_option_set=theme. (unknown)

I think the error of loading the preview in this iFrame is an issue of WP and multisite and the two different link structure (see above). And also the customize.php and admin-ajax.php are files of WP, and not of the theme. But these two php-files of WP are requiered by the framework.php file of the theme (in my case DIVI/Extra).

So far, I will look further. But perhaps you know more or understand more of these files and where the error yould be now?!

Or perhaps an admin of WP here in the support forum can explain it?!

Because many people have this problem, I think WP should find a solution on this topic, because in my eyes it makes no sense that an user always has to change site and homeurl to get the preview, apart from that you cannot call anymore the dashboard of a subsite in the backend of a multisite directly.

Hope for help and to find a comfortable solution for all multisite users in future. Thanks a lot.

All the best, dise?or

Thanks for responding ?? Yes, I am a little be worried about it, to do such changes, because the multisite is running, and I have included until today six subsites, and I will not do something that possibbly could harm it. I could restore it, or better said my provider, but this means that all sites are offline for some hours, and this my client wouldn’t like I think ??

You write, that when you changed these both urls (site and homeURL), your wp-admin login was reachable then unter the domain itself. That means that you then login directly to the domain (https://northstarpulaski.org/wp-admin/) or you (can) login to the multisite and you choose the dashboard of the subsite too?

When I changed the site and homeURL of one of my subsites two days ago, I couldn’t choose anymore the dashboard link of this subsite in the backend of my multisite. The link https://www.my-multisite.de/subsite-folder/wp-admin/ is not running anymore. What do you think is the problem here?

For every domain which directs to a subsite I have four entries in domain mapping:
1. https://my-subsite-domain.de (set to primary)
2. https://www.my-subsite-domain.de
3. https://my-multisite-domain.de/subsite-folder
4. https://www.my-multisite-domain.de/subsite-folder
And for some subsites I have up to eight domains, that means 32 entries I have to do. Is this correct with these four entries each dommain?

Another question: What does this link do when I click on it? When do I have to
to “Upgrade Network”https://www.my-multisite.de/wp-admin/network/upgrade.php? Do I have to upgrade the network when I changed site and homeURL?

Thanks a lot for helping me to clarify on these topic. All the best, dise?or

Thanks for responding so fast. Yes it is a multisite and domain mapping with WordPress MU Domain Mapping, and using subfolders. WP is 4.7.3.

In the beginning I read a lot how to install a multisite, I’ve tried to set it up a few times with existing manuals in internet I was reading on different pages, also with subdomains, but always in this manuals are missing small steps to fulfill it successfully. But for someone who is not really firm in doing this, these small steps are very important. However, at least I could realize it and it is running now. Also I read it would be better to set it up with subfolders, so I decided this way. At another multisite installation we had huge problems, I couldn’t bring it to run. At least the CEO of ServMask helped me to fix it, he looked for it a few days long and tried different ways of code changes, and at least there was an error in the code for the wp-config.php/.htaccess which WP generates automatically (I have bought all plugins from ServMask, and always give feedback on their plugins, therefore he helped me, without him the multisite would not run today). And at another normal WP installation I had a problem too with this code for the .htaccess generated by WP, was also not correct, here the provider where the domain is hosted corrected it.

It is only a sub site. On the main site we have no content at the moment, perhaps later. But another question I have to understand the urls better before I will try to change siteURL and homeUrl. What happens in WP when I change this urls? I don’t know how to explain, but for example in the WP database every data set is based on the multisite url like in my case https://(www.)my-multisite.de. What will happen if I change the site and homeURL to https://my-subsite.de, the data sets will not loose the connection, or how WP handle this, because when I change these both urls will, the urls in the database are not changed too? I have exported once a sub site with the plugin ‘All-in-One WP Migration Multisite Extension’ by ServMask, and then tried to import it again, by changing the multisite url https://www.multisite.de/my-subsite to the domain https://my-subsite.de, but this was not running, I couldn’t call the dashboard of the subsite in the multisite backend; if it were possible by logging in directly with https://my-subsite/wp-admin I don’t know now.

Hope you understand what I will tell you ?? … if not, I will try i again ??

Thanks a lot for your help. Best, dise?or

@andrew Tegenkamp

Thank you for your answer, and sorry for the delayed response.

I tried it. I changed from https://www.my-multisite.de/my-blog/ to https://my-multisite.de/my-blog/ … and the preview in theme customizer is available. BUT then I have the problem, when I click on a dashboard link of one site (blog), it forwards only to the main area of my multisite, and not to the dashboard of the choosed blog anymore. Also, when I try now to login directly to this site/blog, and don’t go over the multisite login, I got the error “no secure login” and cannot type in user/pw. I changed it back with “www” and now it is possible again to login directly to the site, but the preview is not ruuning.

Can I also change in My Sites->NetworkAdmin->Sites the SiteURL and Home(URL) from https://www.my-multisite.de/my-blog/ to https://my-blog.de, so that it doesn’t have the multisite url? I am always worried about changes like this, that perhaps something is not running anymore, that I perhaps cannot change back cause the admin area url is not reachable anymore, so I prefer to ask before I do something like this.

Thanks in advance for responding. All best, dise?or

For Multisite you need to reset these…

My Sites->NetworkAdmin->Sites
Select Edit of offending site
Under Settings == fix both SiteURL and HomeURL

–> there is no field “HomeUrl” to set up at a multisite installation, or I cannot find it?!

Hello. I have the same problem with multisite installation with this error “Non existent changeset UUID“, what means ?no preview“. I know now for sure that the error is the problem with the siteUrl. The plugins aren’t the problem, it is the ‘www.’. But I will explain when the preview will running, and when not.

https://www.my-multisite.tld —> multisite domain
https://www.my-blog.tld —> blog

1a) In ‘domain mapping’ my set up for the blog is:
– https://www.my-blog.tld —> primary domain
– https://my-blog.tld
– https://www.my-multisite.de/myblog
– https://my-multisite.de/myblog

1b) Then ?Network Admin | Sites | Edit Blog | Info/Settings | SiteUrl
(https://www.multisite.de/wp-admin/network/sites.php)

– SiteURL: https://www.my-multisite.de/my-blog/

—> With this setup the preview is not running.

Then I changed the primary domain (1a) to ?https://my-blog.tld (without www)“. No preview again.

Then I changed the SiteURL (1b) to ?https://my-multisite.de/my-blog (without www.)“. Then the preview appears. BUT all Customizer settings are gone, and not only this, also the settings for menus, widgets are gone, this means all things you can handle in the customizer (I use Divi and Extra theme of Elegantthemes) you have to do again.

In the json-file you export in the customizer are only saved colors and font settings, but in this file aren’t saved the ?Site Identity (name)“, Widgets, Menus etc. That means, if we only change this SiteURL (1b), this isn’t the solution.

My Question:
Is it only possible to first export the site via All-in-One-Migration (ServMask) and then import again the blog with changing the domain ?https://my-blog.tld (without www.)“ in the migration process, or there is a possibility without export/import to realize this; perhaps changing some datas in certain files per ftp?

Hope someone can help me/us. Thanks a lot in advanced.

Best regards, dise?or
